A Review of the Welding Things So Far

The acetylene pressure coming out of the hose should never go above ___ PSI

• 15

• 100

• 30

• 25

Which one of these is a good tool for lighting the torch?

• Match

• lit cigarette

• Spark lighter

• An open flame

What is a safe way to check for leaks around ox/acetylene valves, hoses, etc?

• a lit match

• a blow torch

• a lighter

• soapy water

Soapy water tells you that something is leaking on the ox/acetylene torch because:

• it catches fire

• it whistles

• it blows bubbles

• it changes color

The most common tip size used for welding with oxyacetylene is:

• #1

• #2

• #4

• #5

What type of flame do we most often use when using the oxyacetylene torch?

• neutral

• carburizing

• oxidizing

• atomizing

The most common type of welding electrode for SMAW in agriculture is:

• 6011

• 6013

• 7018

• 7014

When you weld using the GMAW process, you must have:

• mayonnaise

• a #5 lens in your helmet

• a box of electrodes

• a bottle of shielding gas like argon/CO2

Which one of these welding processes uses an electrode that does not burn away as you weld?

• GTAW

• GMAW

• TIG

• GTAW and TIG (because they are the same thing)

Which one of these processes works well when you are outside?

• MIG

• TIG

• Flux core

• None of these
